More and more patients are choosing implant treatment to restore missing teeth. Implant restoration includes both implant surgery and post-implant restoration. The criteria for judging the success of dental implant surgery are as follows: 1. At the end of the implant treatment, the implant can withstand the chewing function, can be inactive, and has the strength to support when eating; 2. The mucosa is healthy, and if there is slight inflammation, it can also be effectively controlled by simple treatment; 3. There is no obvious transmissive image around the implant as seen by X-ray, and if there is vertical bone resorption, the amount of resorption needs to be less than 0.2mm per year; 4. After the end of implant treatment, the mandibular nerve canal, maxillary sinus and nasal floor tissues appear to be damaged can be repaired, and at the same time, there will be no continuous inflammation or infection. 5. If the implant treatment is completed and the success rate reaches more than 85% in five years and more than 80% in ten years, the implant treatment is very successful.
